Which of the following will not be seen in zygotene?

(a) Synthesis of Histones

(b) Synthesis of DNA

(c) Formation of synaptonemal complex

(d) Equatorial positioning of chromosomes

The question was posed to me in an international level competition.

The origin of the question is Meiosis Prophase 1 : Zygotene in chapter Chromosomal Changes During Meiosis of Cytogenetics

Correct choice is (d) Equatorial positioning of chromosomes

To explain I would say: Unlike mitosis in meiosis there is both DNA synthesis and histone synthesis for protein compaction in meiosis stage. However, equatorial positioning is seen in metaphase only.
